I switched dentists recently, the old one seemed to see me more in terms of my coverage than my teeth, i.e. what procedures are allowed under the plan, not what are needed.
I chose my new dentist based on my previous experience with him as, at least initially, a team mate on some Ultimate frisbee teams. It was his reputation as a strong defender with a nice flick, more so than any reputation he might have as a dentist, that drew me to him, his reclining chair, and instruments of pain.
You know what they say about Ultimate - it doesn't build character, it conceals it (or something like that).
Successfully transferring reputation across domain boundaries based on sports like volleyball will likely vary.
